Kohler Bathtubs Versus American Standard For A New Bathtub, American Standard Or Kohler?

For a new bathtub, American Standard or Kohler? - kohler bathtubs versus american standard

They were shopping at Home Depot and Lowe's set a new standard towel room. Lowes sells porcelain American Standard Americast tub. Home Depot seems to have Kohler, they are acrylic or cast iron. I wonder if the iron is very heavy and it is difficult to install. Someone knows something about bathtubs?
